We have completed seven hours running on this engine with DES.927 incorporated. These 7 hrs. include 2 hrs. endurance at 472 B.HP. and about 10 mins. at 2750 r.p.m. - the max. permissible speed for 600 B.HP. engine. On dismantling, these bearings were found to be in excellent condition. The engine is being re-built for further development work and we will report on the condition of them in due course.
